Abstract : The purpose of this project is to improve the most critical "bottom-line" characteristic of vertical-cavity microlasers, namely total power efficiency. This improvement will enable the commercialization of large arrays of semiconductor lasers integrated on single chips. Vertical- cavity surface-emitting lasers (VCSELs, tradenamed LASE-ARRAY by Photonics Research Incorporated) are tiny semiconductor lasers, typically about 10 microns in diameter, whose optical cavities and electrical injection schemes are radically different from conventional "edge-emitting" semiconductor lasers. The VCSEL geometry emits high-quality beams perpendicular to the face of the chip, rather than out the edge of the chip, and can be readily fabricated in one- and two- dimensional arrays. (MM)
